On heating, borax first loses water molecules and swells up.On further heating it turns into a transparent liquid, which solidifies into glass like material known as borax bead.

If you take borax and boiling water and make crystals is this a physical change or a chemical change?
It is a chemical change, because the borax reacts to the heated water.
What is the principle behind borax fusion test?
The bead of borax with some powdered sample is heated in a flame; the color of the bead is specific for each element and is used as a qualitative analysis.
Can borax be used as a flux?
Yes, borax, is used as a flux in chemical laboratories.
How man boron atoms are in a molecule of borax?
Borax has four boron atoms.
How does temperature effect borax crystals?
The melting point of borax is 743 oC.
What happen when borax is heated strongly?
When heated borax undergoes various transitions,first it loses water molecules and swells,then it turns into a transparent liquid solidifying to for a glass like structure called borax beads. Na2B4O7.10H20 -->heating Na2B4O7 -->heating 2NaBO2 + B2O3 BORAX SODIUM BORIC METABORATE ANHYDRIDE
How many hydrogen atoms are in a molecule of borax?

Give equations to represent the following reactions.(a) Borax is heated with CaO?
The chemical equation to represent the reaction between borax (Na2B4O7) and CaO (calcium oxide) when heated is: Na2B4O7 + CaO → CaB4O7 + Na2O In this reaction, borax and calcium oxide react to form calcium tetraborate (CaB4O7) and sodium oxide (Na2O) as the products.
What is the principle behind borax fusion test?
The bead of borax with some powdered sample is heated in a flame; the color of the bead is specific for each element and is used as a qualitative analysis.
Can baking soda be substituted for borax in candle wicks?
No, baking soda decomposes when heated to produce carbon dioxide which will extinguish the flame.
Is borax in tide?
Tide does not contain borax as such but contain the same chemical as borax.
